Abstract
The luminescence spectra of noble gases and their binary mixtures were measured using heavy ion beam excitation from a DC-60 accelerator. Spectra were measured in the range of 200-975 nm; the gas spectra were dominated by lines of p-s and d-p atomic transitions; in neon and argon, lines from atomic oxygen, N2, N2 +, and OH radical bands were also observed. The ultraviolet region of the spectra was represented by a third continuum of noble gases. In krypton, the band of the KrO excimer molecule with a maximum at 557 nm was also observed. The maxima of the heteronuclear ionic molecules bands were located at wavelengths of 329 and 506 nm (Ar-Xe), 491 nm (Kr-Xe), and 642 nm (Ar-Kr). The relative intensities of the 2p-1s transitions of the noble gases atoms were measured and are discussed.
